【 摘 要 】

References(9)Cited-By(3)A preliminary study was performed for the extraction of trioxane using supercritical fluids. It is found that carbon dioxide is an effective extractant for trioxane separation and is used as a solvent. The higher is the pressure under the same temperature, the larger amounts of trioxane extracts are obtained. Higher concentrations of trioxane solutions are obtained by supercritical fluid extraction than by common distillation of a trioxane–water.
